They advise in their paper that decisions for lifting anti-epidemic measures need to be prudent and accompanied by close surveillance of the levels of transmission of the virus and rates of hospitalisation. Therefore, there is no guarantee that future variants will be milder, the scientists warn. It belongs to a family of viruses that we know - the coronaviruses - and one of the questions now is whether it will behave like those other viruses. These may escape our immunity and so could be better able to re-infect individuals, and potentially be more severe. The unpredictable antigenic evolution of SARS-CoV-2 will lead to new variants. With the Omicron variant showing 50 nucleic acid changes compared to the original Wuhan strain, SARS-CoV-2 proved to have a high ability to mutate over a relatively short period. Sara Sawyer, a professor of molecular, cellular and developmental biology at the University of. The notion that viruses will evolve to be less virulent to spare their hosts is one of the most persistent myths surrounding pathogen evolution, according to the scientists. Not everyone chooses to wear a mask while riding the subway in New York City, January 28, 2022. However, the paper points out that viruses evolve to maximise their transmissibility and this sometimes may be accompanied by an increase in their pathogenicity. Consequently, European countries are lifting many COVID-19-related restrictions. The first lady had tested positive for the coronavirus last week. Some believed that Omicron signals the beginning of the end of the pandemic, as it leads to less severe symptoms, tending not to attack the lungs. when will covid end Blogs, Comments and Archive.
